2 1. Aim This document summarises road traffic collision data relevant to proposed level crossing closures in Essex. It uses STATS19 data for the period 2013 to 2017 for collisions which occurred in the 12 districts covered by Essex County Council. STATS19 data comprises road traffic collisions resulting in personal injury which occurred on the public highway and were reported to the Police. At the time of writing the data for 2017 has not been finalised for publication by the Department for Transport. We are aware of 3 fatal, 19 serious and 63 slight injury collisions which could be added to the Essex Police 1 data for 2017 before it is published. Data for these collisions is not included in this document. 2. Annual Figures The following tables show the total number of recorded collisions and casualties by year. Collision severity is determined by the most severely injured casualty involved in that collision. Collisions Year Fatal Serious Slight Total ,559 3, ,709 3, ,432 3, ,223 2, ,882 2,566 Total 185 2,892 11,805 14,882 Casualties Year Fatal Serious Slight Total ,428 4, ,731 4, ,320 3, ,151 3, ,744 3,497 Total 194 3,216 16,374 19,784 NOTE: In November 2015 the way casualty severity is recorded was changed, resulting in a jump in the number of recorded serious injuries, and a corresponding drop in the number of slight injuries. 1 Includes the Southend-on-Sea and Thurrock unitary authorities Page 2 of 9

3 3. Data for diversion routes updated 17/07/2018 Data for all sites in this section is for the 5 year period 01/04/2013 to 31/03/2018. This period predates any diversion routes so does not allow a measurement of the future risk to pedestrians who currently use the existing footpaths. a.

6 4. Road Type The table below shows the annual average number of collisions by severity for each road type. Annual average collisions Road Type Fatal Serious Slight Motorway A-road dual carriageway A-road single carriageway B/C roads Unclassified roads The Severity Ratio is the proportion of all injury-collisions which are classed as either serious or fatal. The table below shows that B/C roads have the highest severity ratio, meaning that in the event of a collision, these are the roads where the injuries are most likely to be fatal or serious. Road Type Severity ratio Motorway 18.4% A-road dual carriageway 19.7% A-road single carriageway 20.1% B/C roads 23.0% Unclassified roads 20.4% Data on carriageway lengths makes it possible to calculate the number of collisions per unit of carriageway length. Road Type Carriageway length (km) KSI collisions per 10km All collisions per 10km Motorway A-road dual carriageway A-road single carriageway B/C roads 2, Unclassified roads 4, Page 6 of 9

7 5. Level crossing 1km buffer zones The table below shows the proportion of all recorded collisions which occurred within a 1km radius of a level crossing. Severity Percent within 1km of a level crossing Fatal 10% Serious 8% Slight 9% The locations of these collisions are illustrated on the map below: In numerical terms, this comprises: 18 fatal collisions 238 serious collisions 1,082 slight collisions 18 fatal casualties 255 serious casualties 1,480 slight casualties.over the 5 year period covered by this report Page 7 of 9

8 6. TAG values The DfT produce a data book which estimates the various costs associated with road traffic collisions. It is available to download at: TAG values Fatal Serious Slight Lost Output 727,712 28,786 3,584 Per-casualty Human Costs 1,430, ,136 17,077 values Medical & Ambulance 6,466 17,278 1,520 Total 2,164, ,200 22,182 Per-collision values Police 21,349 2, Damage to Property 13,111 5,980 3,533 Insurance & Admin Total 34,818 8,709 4,315 A large component of the Human costs is defined as the amount of money a sample of the population would be willing to pay for safety improvements in order to avoid the distress and grief resulting from death and injury on the roads. The report IAM Roadsmart, Evaluating the costs of incidents from the public sector perspective" draws out the cashable costs to society, such as ongoing health and social care (H&SC), from the non-cashable component of the human costs. Applying this to current TAG values gives us an estimate of the total financial cost to the economy for each collision and casualty. Per-casualty values Per-collision values 'Cashable' 2018 TAG values Fatal Serious Slight Lost Output 727,712 28,786 3,584 Ongoing H&SC (cashable human costs) 8,227 89,047 9,714 Medical & Ambulance 6,466 17,278 1,520 Total 742, ,110 14,818 The IAM Roadsmart document is available here: Police 21,349 2, Damage to Property 13,111 5,980 3,533 Insurance & Admin Total 34,818 8,709 4,315 There are on average 1.05 fatalities per fatal collision, 1.11 serious casualties per serious collision and 1.39 slight injuries per slight collision. Applying these figures to the collision and casualties costs gives us the following typical total costs per collision: Fatal Serious Slight Financial cost of average collision 815, , , Non cashable cost 1,421, , , Total cost 2,237, , , Page 8 of 9

This figure is taken from the document "IAM Roadsmart, Evaluating the costs of incidents from the public sector perspective". 3) Total financial cost is the total cost to society minus the non-cashable component of human costs. The table above shows these collisions cost the public sector over 9 million per year with a total financial cost of nearly 15.5 million per year. Page 9 of 9
